Succes rate of Cooking

[Tsubaka]

I am trying to find the cooking formula used in HeRo. In RMS's Cooking Calk there is the base level, luck, dex, the level of food, the amount of ingredients and an cooking experience affecting the succes rate. However I have heared that the formula is correct but the cooking experience, and a lot of other stuff affecting or not affecting so play and square my question is:

Does anyone know the succes-rate formula for cooking.
